A search for pair produced charged Higgs bosons was performed on the high energy data collected by DELPHI at LEP2. All three major "nal states, smsm, cssm and cscs were searched for. The analyses used a combination of event shape variables, di-jet masses and jet #avour tagging. The jet #avours were identi"ed by using life time tagging and particle identi"cation based on the RICH detector comple...

Despite the great advances in synthesis and structural determination of atomically precise, thiolate-protected metal nanoclusters, our understanding of the driving forces for their colloidal stabilization is very limited. Currently there is a lack of models able to describe the thermodynamic stability of these 'magic-number' colloidal nanoclusters as a function of their atomic-level structural ...

The main purpose of this paper is to design a charge equalization circuit for series connected lead-acid batteries. The charger utilizes a three-level neutral point clamped (NPC) AC/DC converter with voltage balance control to charge the series connected rechargeable battery strings. This paper details the operation principles of the charge equalization circuit under different operation modes a...

Charge balance functions provide insight into critical issues concerning hadronization and transport in heavy-ion collisions by statistically isolating charge/anti-charge pairs which are correlated by charge conservation. However, distortions from residual interactions and unbalanced charges cloud the observable. Within the context of simple models, the significance of these effects is studied ...

Correlations driven by the constraints of local charge conservation have been shown to provide insight into chemical evolution and diffusivity high-temperature matter created in ultrarelativistic heavy ion collisions. Two-particle correlations final-state interactions allowed extraction critical femtoscopic space-time information about expansion dissolution same Whereas from mainly appear at sm...
